摘要
以过硫酸钾为引发剂 ,硝酸镍为添加剂 ,进行了丙烯酸和丙烯酸羟乙酯 (AAO)及甲基丙烯酸二甲胺乙酯 (DM)的溶液共聚研究 ,制得了吸醇性树脂。研究了树脂的吸醇性能与丙烯酸浓度、引发剂用量和硝酸镍用量的关系 ,同时考察了树脂对不同浓度的异丙醇水溶液的选择性吸收 。
Two absorbentalcohol resins, which was copolymerizated with acrylic acid and AAO or DM, K 2S 2O 8 as initiator,were synthesized by adding Ni(NO 3) 2 in solution. The relationship between the characterization of the resins and concentration of acrylic acid, amount of initiator and Ni(NO 3) 2 were also studied. Those resins can be used to separate isopropanol from its solution.
